Unleash the Monarch Within: Introducing the FX King from FX Airguns

Introducing the FX King: Redefining Precision Hunting

Unleash the monarch within with the revolutionary FX King from FX Airguns. Breaking barriers and redefining innovation, this powerhouse rifle is set to dominate the hunting arena like never before. (Note: Scope & rings pictured are sold separately. RH image used for display purposes.)

Proven Performance: At its core lies the battle-tested block inherited from the Panthera/Dynamic series, ensuring unparalleled power and energy delivery. While excelling as a precision pellet shooter, its true prowess shines when firing slugs, thanks to its innovative valving and slug-centric design, all encased in a sleek GRS stock.

Over-the-Barrel Plenum System: Equipped with an innovative over-the-barrel plenum system akin to other FX models, the FX King maximizes volume advantage for both pellet and slug enthusiasts, all while maintaining a classic sporter stock aesthetic.

Optimized Gauges Placement: Dual-angled high-precision Wika gauges provide real-time monitoring of bottle and regulator pressures, ensuring you never miss a crucial shot, even during intense hunts.

Quick-Tune Integration: Tailor the FX King to your preferences seamlessly with the quick-tune system, integrated into the ergonomic GRS rifle stock for swift, repeatable, and precise adjustments.

Accessory-Ready Design: Enhance your shooting experience with accessory Picatinny rails on both sides of the FX King, offering compatibility with torches, bipods, and more, without compromising its classic sporter rifle profile.

Versatile Ammunition Handling: With a deep magazine design borrowed from the Panthera/Dynamic series, the King effortlessly accommodates various ammunition types, including pellets and slugs up to 13mm in length, ensuring unmatched adaptability in any hunting scenario.

30MOA Picatinny Scope Rail: Crowning the FX King is a 30MOA angled Picatinny scope rail, facilitating extended range shooting with increased elevation adjustments for precision targeting.

Exquisite GRS Stock: Indulge in the luxury of a custom-tailored GRS stock, available in three stunning color options. Crafted by Norwegian stock-making company GRS, it boasts unparalleled adjustability, ergonomic design, and unmatched shooting comfort.

Comprehensive Protection: Each FX King comes nestled in a premium hard case with custom-cut foam, ensuring secure transport and storage, safeguarding your investment for years to come.
